6 Claims. (Cl. 15-262) My invention relates to wringers for squeezing water from mops and is concerned more particularly with providing a device of this nature for domestic service.

Oneobject of my invention is to devise a mop wringer in whichy the squeezing mechanism is foot operated and ismounted on a bucket-like container that is adapted to rest on the floor, thereby eliminating any necessity for stooping during the wringing operation.

A further object is to provide a wringer in which one of the cooperating squeezing rolls is yieldingly mounted to permit the application of a more or less constant squeezing pressure while the mop is being drawn between the rolls.

A further object is the provision of a wringer having squeezing rolls which are adapted to be separated a distance approximately equal to one dimension of the bucket to facilitate the positioning of the mop for squeezing.

A further object is to devise a wringer in which guide members are provided for definitely insuring the locating of the mop strands between the ends of the rolls, thus preventing any possibility of the strands becoming entangled in the axles of the rolls.-

A further object is to provide in a wringer of the type described means for preventing tipping of the bucket during the squeezing operation.

These and further objects of my invention will be set forth in the following specification, reference being had to the accompanying drawings, and the novel means by which said objects are effectuated will be definitely pointed out in the claims.

In the drawings:

, Figure 1 is a plan View of my improved mop wringer showing the squeezing rolls in spaced relation to receive a mop therebetween.

Fig. 2 is a section along vthe line 2--2 in Fig. l, looking in the direction of the arrows.

Fig. 3 is a View similar to Fig. 2, but showing the squeezing rolls in the act of expressing water from a mop placed therebetween.

Fig. 4 is an elevation, partly in section, of a portion of the device, as viewed in the direction of the arrow 4 in Fig. 1, showing the means for returning the treadle to the position indicated in Fig. 2, following its release upon the completion of the squeezing operation.

i Referring to Figs. l and 2 of the drawings, the numeral IIB designates a bucket for holding the liquid in which the mop is dipped. This bucket may have any desired conformation, but is preferably constructed with four flat walls, such as the front wall II, the rear wall I2, and the side walls I3.

A shelf I4 is secured to each side wall I3 adjacent the upper edge thereof and its junction with the front wall I I. A stationary squeezing roll I5 is rotatably mounted on the shelves I4 and eX- tends substantially across the width of the bucket. Each of the shelves extends inwardly beyond the associated outer end of the roll I5 and its inner edge may be shaped as at I6 in order to guide the mop strands into contact with the surface of the roll I5 and denitely prevent any of the strands from becoming entangled with the axle of the indicated roll. y.

Within the bucket, a plate I'I is secured to the inner face of each side wall I3 and this plate is preferably formed with an elongated shape and symmetrically disposed with reference to the vertical center line of the associated side wall for a purpose hereinafter explained. A rock arm I8 is pivotally mounted as at I9 on each plate I1 and each arm is provided with a ledge against which bears one end of a plunger 2| that is slidably mounted in a sleeve 22 which is also pivoted on the associated rock arm I8. One end of the f sleeve 22 is closed by an adjustable plug 23 (see Fig. 3) and between this plug and the adjacent end of the plunger 2| is located a coil spring 24 which always causes the plunger 2| tobear against the ledge 20 and normally maintain the sleeve in the position shown in the drawings.

Each sleeve 22 is provided with an extension 25 and between these extensions is bridged a second squeezing roll 26 which is appropriately rotatably mounted upon a suitable axle extending between the indicated extensions. In order to facilitate the squeezing action, the roll 26 may have its squeezing surface curved as indicated in Fig. 1.

One end of a link 21 is pivotally connected to the arm I8 and the opposite end is pivotally connected to a rock arm 28 which is xed toa pin 29 that is rotatably mounted in the plate I'I and extends outwardly through the wall I3, it being understood that-the construction just referred to is arranged on both of the side walls I3.

Arms 30 are secured on the outer ends of the pins 29, respectively, and extend forwardly of the front wall II for securement toa cross bar 3| to form a foot treadle 32. Preferably, a foot rest 33 is secured to the intermediate portion of the treadle 32 and may have its upper edge roughened to prevent slippage of the foot.

Referring to Fig. 4, and also to Fig. 1, it will be noted that these arms 3Il,are spaced somewhat from the adjacent side walls to permit the mounting of a coil spring 34 around the exposed portions of the pins 29. One end 35 of each of these springs is looped under the adjacent arm 30, while the opposite end 3E is received within a suitable pocket 3l provided on a plate 38 which is externally secured to the adjacent side wall I3. The usual bail 39 for carrying the bucket I D is secured to the plates 38. l0 For a purpose presently explained, a foot piece 40 is located forwardly of the front wall II and is connected to the bucket by an appropriate frame 4I.

Figs. 1 and 2 illustrate the disposition of the squeezing mechanism when in retracted or nonoperative position. Under these conditions it will be particularly noted that the squeezing rolls are fully spaced apart to a distance that approximates one dimension of the bucket, thereby providing free access to the interior of the bucket,

such as for the dipping of the mop.

When it is desired to squeeze the mop, it is simply necessary to insert the mop in the bucket with the portion of the mop adjacent the handle thereof contacting the stationary roll I5. The operator then presses downwardly on the treadle 32 to thereby swing the roll 26 to the position shown in Fig. 3, whereupon the mop is drawn upwardly between the rolls and the pressure created through the treadle serves to express the water from the mop. During this operation, it will be particularly noted that it is possible to exert a substantially constant pressure against the mop, because of the yieldable mounting of 35 the squeezing roll 26. This construction obviates any necessity for relieving pressure on the treadle in the event that extensive bulges or hard formations are encountered in the mop while the latter is being drawn upwardly. Moreover,

due to the fact that each of the sleeves 22 is oiset from the associated pivot i9 toward the rear wall I2 and forms with the attached extension 25 the limbs of the letter V, it is possible to retain the axis of the roll 2B within the confines of the bucket during its movement to and from squeezing position and to also insure that the sleeves will be well spaced from the mop strands during squeezing to prevent interference. The foregoing disposition also enables the roll 26 to be retracted the maximum distance as permitted by the dimensions of the bucket. The shelf I4 serves to definitely guide the mop strands into the proper position for being squeezed, while the foot 40 prevents any tendency of the bucket to tip during the squeezing operation.
